Panic on EventFrameRequestedNavigation with stale frame

[ankur22]

Brief summary

When we get a EventFrameRequestedNavigation CDP event from chrome, it might be associated to a stale frame that no longer exists in memory. This is the stack trace that we see:

panic: GoError: handling frameRequestedNavigation event to "https://...": no frame exists with ID DB9E6F291E31070542D4EDD570CBC4E3

The fix is to not return an error from frameRequestedNavigation when frame == nil, and instead just return nil (no error).

It's the same in PW (1 -> 2).
